How many turbines are needed to power a household or farm?
For a home or farm, one turbine with a power rating of anywhere from 1kW to 25kW is normally installed. The turbine’s size is chosen to meet the energy requirements given the available wind resource. Buying multiple turbines for one application rather than a single larger one is almost always less economical because of the cost of buying two separate towers and installing two separate systems. For village electrification applications, both single and multiple turbine installations are common, and turbines up to 100 kW in capacity may be used.
